Show HN: PassDetective – Scan your shell history for leaked passwords and secret

Hi HN, I built PassDetective after realizing how often passwords, tokens, and secrets accidentally end up in shell history during debugging or quick tests. PassDetective is a small CLI tool that scans shell history files using pattern matching to flag potential secrets before they get committed, backed up, or shared. It currently works on Kali Linux and NixOS, and is meant to be a lightweight, local-first check rather than a full secret scanning solution. I’d appreciate feedback on false positives, missing patterns, or how people approach this problem in their own workflows.
